From b55cd4bc1e6fd33da4755ea7eea079967716b366 Mon Sep 17 00:00:00 2001 From: hailin Date: Sat, 7 Feb 2026 10:25:59 -0800 Subject: [PATCH] fix(agents): widen answer length limits and preserve followUp continuations MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit INTENT_MAX_ANSWER_LENGTH was too tight (objection_expression 200 chars truncated good responses). Bumped all limits ~25-50%. Also fixed followUp filter that silently dropped content when model split answer across answer+followUp fields — now appends followUp as continuation when answer ends mid-sentence.
